I-25/Dry Creek Rd Interchange Corridor Study
Study Area, Purpose and Goals
Arapahoe County, in conjunction with the City of Centennial and the Southeast Public Improvement Metropolitan District, conducted the I-25/Dry Creek Road Interchange and Corridor Study in 2015-2017. The study area included Dry Creek Road from Yosemite Street to Easter Avenue, including the I-25 interchange. The purpose of the study was to consider short-term and long-term improvements to address peak period congestion along the corridor. Study goals were to develop a range of improvements to:
- Improve regional access
- Improve mobility and reliability of the system
- Improve congestion and safety
- Optimize existing infrastructure
- Leverage past area transportation investments
- Consider all modes of transportation
Over the next 25 years and beyond, the I-25/Dry Creek Road interchange and corridor between Yosemite Street and Easter Avenue will serve as an important facility for both local and regional travel. Dry Creek Road will provide an appropriate balance of improved traffic operations, multimodal mobility, and safety while maintaining local accessibility. Planned improvements will minimize impacts to existing neighborhoods, maintain the community identity, and match the neighborhood/mixed use surroundings.
Study recommendations are described in the Final Study Report and illustrated in these graphics.
